Zertalin is used for treating mild to moderate infections caused by certain bacteria. It may also be
used
alone or with other medicines to treat or prevent certain infections in persons with advanced HIV
infection.
Zertalin is a macrolide antibiotic. It slows the growth of, or sometimes kills, sensitive bacteria by
reducing the production of important proteins needed by the bacteria to survive.

Description

Zertalinis available as both a generic and brand-name drug. Brand name(s): Zithromax. Generic drugs
usually cost less than the brand-name version.

Zertalinis used to treat infections caused by bacteria.

This drug comes as a tablet, suspension, and extended-release suspension you take by mouth. It also
comes
as eye drops, as well as an intravenous form given by healthcare provider.

Zertalinis a prescription drug.

Zertalinis used to treat certain infections caused by bacteria. It should not be used to treat
infections caused by viruses, such as the common cold. Zertalinmay be used in combination with other
antibiotics when it’s used to treat mycobacterium avium complex infection.

Zertalinworks by stopping bacteria from multiplying. This kills the bacteria and treats your
infection.

Dosage

Take this medication exactly as it was prescribed for you. Do not take the medication in larger
amounts,
or take it for longer than recommended by your doctor. The dose and length of treatment with Zertalin may
not
be the same for every type of infection. Take each tablet or capsule with a full glass (8 ounces) of
water.
To use the oral suspension single dose packet: Open the packet and pour the medicine into 2 ounces of
water.
Stir this mixture and drink all of it right away. To make sure you get the entire dose, add a little
more
water to the same glass, swirl gently and drink right away. Zertalin capsules must be taken on an empty
stomach. Take the capsule at least 1 hour before or 2 hours after eating a meal Zertalin tablets or powder
oral suspension may be taken with or without food. Take the tablet or oral suspension with food if the
medicine upsets your stomach. Do not take Zertalin at the same time as taking an antacid that contains
aluminum or magnesium. This includes Rolaids, Maalox, Mylanta, Milk of Magnesia, Pepcid Complete, and
others. These antacids can make Zertalin less effective when taken at the same time. Shake the oral
suspension (liquid) well just before you measure a dose. To be sure you get the correct dose, measure
the
liquid with a marked measuring spoon or medicine cup, not with a regular table spoon. If you do not have
a
dose-measuring device, ask your pharmacist for one. Take this medication for the entire length of time
prescribed by your doctor. Your symptoms may get better before the infection is completely treated.
Zertalin
will not treat a viral infection such as the common cold or flu. It is important to take Zertalin
regularly
to get the most benefit. Store this medication at room temperature away from moisture and heat. Throw
away
any unused liquid medicine after 10 days.

Overdose

Seek emergency medical attention if you think you have used too much of this medicine. Symptoms of an
Zertalin overdose may include nausea, vomiting, diarrhea, and stomach discomfort.

Storage

Store at room temperature between 15 and 30 degrees C (59 and 86 degrees F) away from moisture and heat. Throw away any unused medicine after the expiration date. Keep out of reach of children in a container that small children cannot open.

Although long-term azithromycin decreases exacerbation frequency in bronchiectasis, increased macrolide resistance is concerning. We investigated macrolide resistance determinants in a secondary analysis of a multicenter randomized controlled trial. Indigenous Australian children living in remote regions and urban New Zealand Māori and Pacific Islander children with bronchiectasis were randomized to weekly azithromycin (30 mg/kg) or placebo for up to 24 months and followed post-intervention for up to 12 months. Nurses administered and recorded medications given and collected nasopharyngeal swabs 3-6 monthly for culture and antimicrobial susceptibility testing. Nasopharyngeal carriage of Haemophilus influenzae and Moraxella catarrhalis was significantly lower in azithromycin compared to placebo groups, while macrolide-resistant Streptococcus pneumoniae and Staphylococcus aureus carriage was significantly higher. Australian children, compared to New Zealand children, had higher carriage overall, significantly higher carriage of macrolide-resistant bacteria at baseline (16/38 versus 2/40 children) and during the intervention (69/152 versus 22/239 swabs), and lower mean adherence to study medication (63 % versus 92 %). Adherence ≥70 % (versus <70 %) in the Australian azithromycin group was associated with lower carriage of any pathogen [odds ratio (OR) 0.19, 95 % confidence interval (CI) 0.07-0.53] and fewer macrolide-resistant pathogens (OR 0.34, 95 % CI 0.14-0.81). Post-intervention (median 6 months), macrolide resistance in S. pneumoniae declined significantly in the azithromycin group, from 79 % (11/14) to 7 % (1/14) of positive swabs, but S. aureus strains remained 100 % macrolide resistant. Azithromycin treatment, the Australian remote setting, and adherence <70 % were significant independent determinants of macrolide resistance in children with bronchiectasis. Adherence to treatment may limit macrolide resistance by suppressing carriage.

Non-gonococcal urethritis (NGU), or inflammation of the urethra, is the most common treatable sexually transmitted syndrome in men, with approximately 20-50 % of cases being due to infection with Chlamydia trachomatis and 10-30 % Mycoplasma genitalium. Other causes are Ureaplasma urealyticum, Trichomonas vaginalis, anaerobes, Herpes simplex virus (HSV) and adenovirus. Up to half of the cases are non-specific. Urethritis is characterized by discharge, dysuria and/or urethral discomfort but may be asymptomatic. The diagnosis of urethritis is confirmed by demonstrating an excess of polymorpho-nuclear leucocytes (PMNLs) in a stained smear. An excess of mononuclear leucocytes in the smear indicates a viral etiology. In patients presenting with symptoms of urethritis, the diagnosis should be confirmed by microscopy of a stained smear, ruling out gonorrhea. Nucleid acid amplifications tests (NAAT) for Neisseria gonorrhoeae, C. trachomatis and for M. genitalium. If viral or protozoan aetiology is suspected, NAAT for HSV, adenovirus and T. vaginalis, if available. If marked symptoms and urethritis is confirmed, syndromic treatment should be given at the first appointment without waiting for the laboratory results. Treatment options are doxycycline 100 mg x 2 for one week or azithromycin 1 gram single dose or 1,5 gram distributed in five days. However, azithromycin as first line treatment without test of cure for M. genitalium and subsequent Moxifloxacin treatment of macrolide resistant strains will select and increase the macrolide resistant strains in the population. If positive for M. genitalium, test of cure samples should be collected no earlier than three weeks after start of treatment. If positive in test of cure, moxifloxacin 400 mg 7-14 days is indicated. Current partner(s) should be tested and treated with the same regimen. They should abstain from intercourse until both have completed treatment. Persistent or recurrent NGU must be confirmed with microscopy. Reinfection and compliance must be considered. Evidence for the following recommendations is limited, and is based on clinical experience and guidelines. If doxycycline was given as first therapy, azithromycin five days plus metronidazole 4-500 mg twice daily for 5-7 days should be given. If azithromycin was prescribed as first therapy, doxycycline 100 mg x 2 for one week plus metronidazole, or moxifloxacin 400 mg orally once daily for 7-14 days should be given.

A 50-year-old man with alcoholic liver disease presented with fever, tenosynovitis, polyarthritis and a vasculitic rash on the hands and feet for 4 days. He had neutrophilia and raised inflammatory markers. He had no history of sore throat, urethral discharge or travel abroad. His initial blood cultures were negative, and he was treated for vasculitis with steroids. The rash and arthritis seemed to improve initially, but he had another episode of fever. Repeat blood cultures grew Neisseria gonorrhoeae,and he received intravenous ceftriaxone followed by oral ciprofloxacin. He had marked improvement in rash, tenosynovitis and arthritis, and the fever dropped. He also had chlamydial urethritis and received azithromycin. The presentation of disseminated gonococcal infection after a presumptive episode of asymptomatic urethral gonorrhoea is highlighted.

Azithromycin did not improve the immunogenicity of oral poliovirus vaccine despite reducing biomarkers of environmental enteropathy and the prevalence of pathogenic intestinal bacteria. Viral interference and innate antiviral immune mechanisms might be more important determinants of the immunogenicity of live-virus oral vaccines.

The efficacy and tolerability of azithromycin and erythromycin in the treatment of acute respiratory tract infections in children were compared in an open, multicenter, randomized trial. A total of 151 children, aged from 2 months to 14 years, suffering from upper airways infections (60), or lower respiratory tract infections (91), were randomized to be treated either with azithromycin, 10 mg/Kg/day per os once daily for 3 or 10 mg/Kg/day 1 and 5 mg/Kg/days 2-5 (77 patients) or with erythromycin, 50 mg/Kg/day thrice daily for at least 7 days (74 patients). The two treatment groups did not significantly differ as to sex, age, weight, type and severity of infection, and infecting pathogens. Clinical evaluation was performed prior to therapy, on treatment days 1, 3, 5 and 7, and on day 10. Microbiological and laboratory assessment were carried out at baseline and after the end of therapeutic course. Chest X-ray and serologic assays for Mycoplasma pneumoniae infection were obtained in patients suspected to have lower respiratory tract infections. At the end of therapy, clinical cure was achieved in 73 out of 77 patients (94.8%) in the azithromycin group, and in 60/72 evaluable subjects (83.3%) in the erythromycin group. A significantly more rapid remission of several illness-related signs and symptoms was observed in patients treated with azithromycin. A total of 75 bacterial pathogens were isolated at baseline microbiological examination; at the end of the therapeutic course bacteriological eradication was obtained in 34/34 cases (100%) treated with azithromycin, and in 40/41 children (97.5%) treated with erythromycin.(ABSTRACT TRUNCATED AT 250 WORDS)

The conventionally used dose of isotretinoin in acne causes significant dose-related adverse effects. Low-dose isotretinoin has been used successfully in mild to moderate papulopustular acne. Although isotretinoin acts against all mechanisms of acne formation, it has no significant direct antimicrobial effect.

Consecutive eligible M. genitalium-infected men and women attending the Melbourne Sexual Health Centre between July 2012 and June 2013 were treated with 1 g of azithromycin and retested by polymerase chain reaction (PCR) on days 14 and 28. Cure was defined as PCR negative on day 28. Cases failing azithromycin were treated with moxifloxacin, and those failing moxifloxacin were treated with pristinamycin. Pre- and posttreatment samples were assessed for macrolide resistance mutations (MRMs) by high-resolution melt analysis. Mycoplasma genitalium samples from cases failing moxifloxacin were sequenced for fluoroquinolone resistance mutations. Multivariable analysis was used to examine associations with azithromycin failure.

From May 1995 to May 1996, thirty-six females with chlamydial cervicitis were enrolled at Bangrak Hospital's Venereal Disease Clinic in an open study to assess the efficacy and safety of a single, 1-gram oral dose of azithromycin. Thirty-five had positive C. trachomatis and one had a positive Gen-probe test. Twenty-two returned for their first and second follow-ups and 18 came back for their final follow-up (visit 4). Eradication rate was 100 per cent on all visits. Fourteen patients were excluded from the final analysis- three had dropped out from the beginning, ten had sexual intercourse without a condom and one had a positive Gen-probe Sulfamethoxazole Tmp Ds Tablet test but negative C. trachomatis culture. U. urealyticum was isolated from the vaginal wall of 15 of the 36 cases and eradication rate was 0 per cent at visit 2 and visit 4. In conclusion, this study shows that a single, 1-gram oral dose of azithromycin is an effective and well-tolerated alternative therapy for chlamydial cervicitis.

To compare the clinical and microbiological efficacy of azithromycin in curing chlamydial infections in women with that of lymecycline, and with a view of the possibility of minimizing the problem of compliance by means of single-dose administration, 146 women with culture-positive Chlamydia trachomatis infections were randomly assigned to treatment with a 1 g bolus dose of azithromycin or a 10-day course of lymecycline 300 mg twice daily. Clinical and microbiological evaluations were performed and adverse effects monitored at check-ups after 15-35 and 40-65 days. Of the 146 patients enrolled in the study, 120 were evaluable. At the second check-up, C. trachomatis was found to have been eradicated in all patients in both treatment groups. Of the 51 patients who had clinical signs and symptoms of genital infection at enrolment, 96% (22/23) of those in the azithromycin group were considered cured (n = 18) or improved (n = 4), as compared with 100% (28/28) of those considered cured (n = 22) or improved (n = 6) in the lymecycline group. Adverse events related, or possibly related, to treatment were reported by 16 (21.6%) of the lymecycline group, but by only 6 (8.3%) of the azithromycin group. The 2 drugs were comparable with regard to microbiological and clinical efficacy in the treatment of genital chlamydial Septrin Dose infection in women. The markedly lower rate of side-effects associated with azithromycin may be a feature conducive to patient compliance.

Streptococcus agalactiae UCN70, isolated from a vaginal swab obtained in New Zealand, is resistant to lincosamides and streptogramins A (LS(A) phenotype) and also to tiamulin (a pleuromutilin). By whole-genome sequencing, we identified a 5,224-bp chromosomal extra-element that comprised a 1,479-bp open reading frame coding for an ABC protein (492 amino acids) 45% identical to Lsa(A), a protein related to intrinsic LS(A) resistance in Enterococcus faecalis. Expression of this novel gene, named lsa(C), in S. agalactiae BM132 after cloning led to an increase in MICs of lincomycin (0.06 to 4 μg/ml), clindamycin (0.03 to 2 μg/ml), dalfopristin (2 to >32 μg/ml), and tiamulin (0.12 to 32 μg/ml), whereas no change in MICs of erythromycin (0.06 μg/ml), azithromycin (0.03 μg/ml), spiramycin (0 Azenil 200 Mg .25 μg/ml), telithromycin (0.03 μg/ml), and quinupristin (8 μg/ml) was observed. The phenotype was renamed the LS(A)P phenotype on the basis of cross-resistance to lincosamides, streptogramins A, and pleuromutilins. This gene was also identified in similar genetic environments in 17 other S. agalactiae clinical isolates from New Zealand exhibiting the same LS(A)P phenotype, whereas it was absent in susceptible S. agalactiae strains. Interestingly, this extra-element was bracketed by a 7-bp duplication of a target site (ATTAGAA), suggesting that this structure was likely a mobile genetic element. In conclusion, we identified a novel gene, lsa(C), responsible for the acquired LS(A)P resistance phenotype in S. agalactiae. Dissection of the biochemical basis of resistance, as well as demonstration of in vitro mobilization of lsa(C), remains to be performed.

To evaluate the efficacy of single dose Azithromycin (1 gram) in treatment of cholera in adults. A randomized, controlled clinical trial on 120 adults with acute watery diarrhoea and moderate to severe dehydration compared the efficacy of azithromycin (1 gram) single dose and Norfloxacin (400 mg) twice daily for three days in treating cholera. Data were analysed for 64 patients who were stool culture positive for Vibrio cholerae. In conjunction with rehydration therapy, 32 patients received Azithromycin and 32 patients received Norfloxacin. Patients in the two treatment groups had comparable clinical characteristics Mahacef 200 Mg Tablet on admission.

Azithromycin exhibited in-vitro activity against 20 clinical isolates of Mycobacterium avium complex for which the MIC90 was 32 mg/L and 22 clinical isolates of other mycobacteria but showed no activity against 20 isolates of Mycobacterium tuberculosis (MIC90 > 128 mg/L) nor against the single isolate of Mycobacterium marinum tested (MIC 128 mg/L Klerimed 500 Mg Tablety ). These results suggest that the drug may prove useful for the prophylaxis and treatment of infections due to non-tuberculous mycobacteria, including M. avium complex in patients with AIDS.

Rhodococcus equi is an opportunistic pathogen that usually causes infection in immunocompromised hosts. A heart transplant recipient who had been treated with amphotericin B for pulmonary aspergillosis showed newly developed multiple nodules with a central necrotic area in the right lower lobes. Cultures of several blood samples and an aspirate of the lung nodule yielded a Gram-positive coccobacillary bacterium, which was initially reported as a Corynebacterium Macrol Dosage species, but was later identified as R. equi by API CORYNE (bioMerieux SA, Marcy l'Etoile, France) and by demonstrating the production of 'equi factor'. The identification was subsequently confirmed by an R. equi-specific polymerase chain reaction (PCR). The patient was successfully treated with ciprofloxacin and azithromycin for 14 weeks. This is the first documented case of R. equi infection in Korea. There is a possibility of underestimation of R. equi infections due to the misidentification of the organism as a contaminating diphtheroid. Because R. equi will not respond to the conventional empirical therapy, the microbiology laboratory should identify R. equi in a timely manner. R. equi-specific PCR will be a useful confirmatory test in human infection.
